As season 2014 begins today, we explain some of the rule changes from now on...
The previously-legal lower beam wing has been outlawed and the main flap has become slightly shallower in profile. Support pillars, however, are allowed this time.
Cars will have one extra gear to combat the reduced fuel. However, a gearbox must now last six consecutive races and not five as earlier.
As the new engines produce less power, a larger part of a car's power will come from Energy Recovery System. Besides generating energy under braking, ERS also generates power using waste heat from the engine. The ERS can supply 10 times more energy per lap than the Kinetic Energy Recovery System used last season.
The height of the nose has been restricted to 185mm from 550mm to reduce possibility of cars being launched into the air like Mark Webber's car (2010 Euroipean GP).
The 1.6-litre V6 turbo engines produce less power than their predecessor — the V8. However, they are more economical and are seen as the future of the automotive industry.
Front wings will be a little narrower with the width reduced from 1800mm to 1650mm.
To promote fuel efficiency, each car can only use 100kg of fuel per race. Previously, there was no cap on fuel.
As the power components now are heavier, the car's min weight has been increased from last year's 642kg to 691kg.
Drivers who appear in Q3 will get an extra set of tyres. They will start the race using their fastest-lap tyres from Q2.
Drivers who earn 12 penalty points in a 12-month period will get a one-race ban. There will be five-second penalties for minor offences.
In the last race (Abu Dhabi GP) drivers will be awarded double points. This ensures the championship race stays open longer.
